Hey everybody, just recently bought a 2009 Cadillac CTSV that is black. It is my daily driver but I try to wash it in my garage every weekend. We usually only have a few weeks where the temp drops down into freezing but we do get snow those weeks. I ordered the Forum Favorite kit that has the Klass All in one and the Pinnacle paste wax for the summer time but want to know if I should I do something else for the winter months for more harsher weather. I want something that will withstand the nasty roads and weekly washing. I was looking at Detailer's Poli-Coat Paint Sealant and Collinite Liquid Insulator Wax #845 which comes in a kit for $29.99. Its write up mentions about nasty cold weather protection a lot. Just wondering if this is a good idea or what others do for the daily driver for the winter months.
